Abstract

PURPOSE:To unify radiation temperature distribution and improve energy efficiency, by a method wherein radiating sections are provided in the form of waves and hot air supplying tubes are constituted at the inside of the radiating sections while spaces in the recesses of the radiating sections are partitioned from other space. CONSTITUTION:Hot air, supplied into hot air supplying tubes 4, is injected from injection ports 9 into spaces 5 in the recesses of radiating sections to heat the radiating sections 3. The hot air, whose temperature is reduced, is injected from gaps 8 into the other spaces 6 of the radiating body 1 while increasing the flow speed and is discharged into atmosphere through a discharging part constituted at a proper place. The radiating sections 3 are heated by the hot air injected through the injection ports 9; therefore, the surface temperature of the radiating sections 3 may be unified in the lengthwise direction of the same sections 3. The spaces 5 in the recesses are partitioned from other spaces 6 by partitioning plates 7 while the hot air is injected into the spaces 5 only, therefore, only the radiating sections 3 may be heated efficiently.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a radiant member of a radiant heater device used for various heating processes, space heating, and the like.

(Prior art and its problems) In a conventional radiant heater device that has a radiant surface with a large area, as shown in Fig. 4, a radiant tube that passes hot air from a hot air supply source a such as a burner is It can be configured as a radiator with a wide area by being arranged in a plane, or it can be configured as a flat cylinder d with a corrugated radiator plate C on one side and hot air passed inside as shown in Figure f$5.
is constructed as a radiator with a wide area.

However, in the past, hot air was simply passed directly through the radiator from the upstream side to the downstream side, so the temperature of the hot air and the temperature of the radiating surface decreased as it went downstream, thus controlling the radiation wavelength depending on the temperature. In addition, there is a problem in that energy efficiency is low because the radiant tube is heated in areas other than those corresponding to the predetermined radiation direction.

The present invention aims to solve the above problems.

(Means for Solving the Problems) The configuration of the present invention will be explained based on FIGS. 1 to 3 corresponding to the embodiment. On the side plate body 2, outwardly convex radiating parts 3 are arranged in a wave-like manner, and a hot air supply pipe 4 is formed in the recessed part inside each of the radiating parts 3, and a space 5 inside the recessed part and another space 6 are formed. A partition plate γ for partitioning is constructed between the hot air supply pipe 4 and the plate body 2, and a hot air communication gap 8 is provided on the plate body 2 side of the partition plate 7.
In addition, a JA wind bath outlet 9 is disposed in the longitudinal direction on the side of the recess inner space 5 of the FiiJ hot air supply pipe 4.

(Function) In the above configuration, the hot air supplied to the hot air supply pipe 4 is
It is ejected from the ejection port 9 into the recess inner space 5, and the radiant part 3fr
:Heat. Then, the hot air whose temperature has decreased is then ejected from the gap 8 into the other space 6 of the i-enclosed body 1 at an increased flow velocity,
It is discharged into the outside air through the space 6 from a discharge section configured at a suitable location.

In this way, in the present invention, the three radiating parts of the radiator 1,
Since heating is performed by hot air blown out from each hot air outlet 9 arranged in the length direction of the hot air supply pipe 4, the inside of the radiator 1 is directly heated with zero force by the hot air flowing from the upstream side to the downstream side. Unlike the structure shown in FIG. 1, the surface temperature does not decrease as it goes downstream, and the surface temperature of the radiant section 3 can be made uniform in the length direction. Therefore, the radiating parts 3 arranged in a row
PAIR of a burner etc. is connected to the hot air supply pipe 4 corresponding to each of the
By supplying hot air under the same conditions kc through the header pipe connected to the A supply source, it is possible to equalize the surface temperature of all the radiant parts 3.

Further, the recessed space 5 inside the radiant section 3 is separated from other spaces 6 by a partition plate 7, and the hot air supplied to the hot air supply pipe 4 is ejected from the hot air outlet 9 only into this space 5. , and after heating the radiant part 3, the flow is ejected from the gap 8 into the other space 6 at an increased flow rate, so that the radiant part 3
, it is possible to efficiently heat the roof and increase energy efficiency.

(Example) Next, an example will be explained. In the example shown in FIG.
One end of the hot air supply pipe 4 corresponding to each radiant section 3 is connected to a header 111Cffl connected to a hot air supply source 10 such as a burner.
At the same time, the other end is closed. In addition, a perforated plate 12 is provided on the rear side of the radiator 1 and on the opposite side of the plate body 2, and from here P! It is configured to emit S wind.

With the above configuration, all the hot air from the hot air supply source 10 passes through the respective hot air supply pipes 4 and is discharged from the PA air bath outlet 9 to the recess inner space 5 9, and all the hot air in this space 5 also flows through the gap 8. It is ejected into the other space 6 and released into the outside air from the pores 812, thus making it possible to equalize the radiant temperature and save energy for the radiant section 3 of the radiator 1 over a wide area. It is. In a specific design, the radiation temperature in the length direction of the radiant portion 3 can be easily made uniform by, for example, setting the diameter of the heat ejection port 9 and its distribution state in the length direction. The reference numeral 13 in the figure is a desired radiant material formed on the outside of the radiant portion 3.
Such radiant material 13Fi may be omitted depending on the case. In addition to the above-mentioned perforated plate 12, the part for discharging hot air to the outside air can also be configured at an appropriate location.

(Effects of the Invention) As described above, the present invention differs from the conventional radiator in which hot air is directly directed inside and flows from the upstream side to the downstream side to heat the radiant area. A hot air supply pipe is formed in each of the recesses inside the part, and the radiant part is heated by the hot air ejected into the hot air supply pipe, and the hot air is distributed only within the recess space partitioned by the partition plate. Since the VCClt is configured to eject water, then increase the flow velocity from the gap between the partition plates and eject it into other spaces,
The surface temperature of the radiant part can be made uniform in the length direction,
Therefore, the radiation temperature distribution can be made uniform over a wide area of the radiation surface, and the temperature-dependent radiation wavelength can be easily controlled, and energy efficiency can be improved.
